Question 7547: an algebra teacher stated that 2x+1=1 5=2x=14 are equivalent. what was done to the first equation to get the second equation? what is the value of x that makes both equations equal?

You can put this solution on YOUR website!
To get from 2x%2B1=15 to 2x=14, you would subtract 1 from both sides of the first equation.
To find the value of x that makes these equations equivalent, in 2x+=+14, divide both sides by 2.
2x+=+14 Divide both sides by 2.
x+=+7
You can check this yourself by substituting 7 for x in each equation.
